Reliable democratic (er, GROPelite) Senators.
The GOP senate is not anything but reliable shills for the bureaucracy and their good friends from across the aisle. If the crap hits the fan with the release of this memo count on the GOP senate to defend their bosses in the deep state. They are useless as a screen door on a submarine and as cowardly as can be humanly possible.
